    <p>Everything is working fine in my rails project, except for one thing. I'm trying to be able to edit a boolean with check_box. But when I go to edit, whether or not the check_box is checked, the boolean stays false. Here is my relevant code:</p> <pre><code>class SubnetsController &lt; ApplicationController # GET /subnets # GET /subnets.json def index @subnets = Subnet.all respond_to do |format| format.html # index.html.erb format.json { render :json =&gt; @subnets } end end def normal @subnets = Subnet.all respond_to do |format| format.html # normal.html.erb format.json { render :json =&gt; @subnets } end end # GET /subnets/1 # GET /subnets/1.json def show @subnet = Subnet.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json { render :json =&gt; @subnet } end end # GET /subnets/new # GET /subnets/new.json def new @subnet = Subnet.new respond_to do |format| format.html # new.html.erb format.json { render :json =&gt; @subnet } end end # GET /subnets/1/edit def edit @subnet = Subnet.find(params[:id]) end # POST /subnets # POST /subnets.json def create @subnet = Subnet.new(params[:subnet]) respond_to do |format| if @subnet.save format.html { redirect_to @subnet, :notice =&gt; 'Subnet was successfully created.' } format.json { render :json =&gt; @subnet, :status =&gt; :created, :location =&gt; @subnet } else format.html { render :action =&gt; "new" } format.json { render :json =&gt; @subnet.errors, :status =&gt; :unprocessable_entity } end end end # PUT /subnets/1 # PUT /subnets/1.json def update @subnet = Subnet.find(params[:id]) respond_to do |format| if @subnet.update_attributes(params[:subnet]) format.html { redirect_to @subnet, :notice =&gt; 'Subnet was successfully updated.' } format.json { head :no_content } else format.html { render :action =&gt; "edit" } format.json { render :json =&gt; @subnet.errors, :status =&gt; :unprocessable_entity } end end end # DELETE /subnets/1 # DELETE /subnets/1.json def destroy @subnet = Subnet.find(params[:id]) @subnet.destroy respond_to do |format| format.html { redirect_to subnets_url } format.json { head :no_content } end end end </code></pre> <p>View:</p> <pre><code>&lt;%= form_for(@subnet) do |f| %&gt; &lt;% if @subnet.errors.any? %&gt; &lt;div id="error_explanation"&gt; &lt;h2&gt;&lt;%= pluralize(@subnet.errors.count, "error") %&gt; prohibited this subnet from being saved:&lt;/h2&gt; &lt;ul&gt; &lt;% @subnet.errors.full_messages.each do |msg| %&gt; &lt;li&gt;&lt;%= msg %&gt;&lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;/div&gt; &lt;% end %&gt; &lt;div class="field"&gt; &lt;%= f.label :SubnetName %&gt;&lt;br /&gt; &lt;%= f.text_field :SubnetName %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :FW_Context_BridgeGroup %&gt;&lt;br /&gt; &lt;%= f.number_field :FW_Context_BridgeGroup %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :VlanNumber %&gt;&lt;br /&gt; &lt;%= f.number_field :VlanNumber %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :FwVlan %&gt;&lt;br /&gt; &lt;%= f.number_field :FwVlan %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :NetAddress %&gt;&lt;br /&gt; &lt;%= f.text_field :NetAddress %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :DefaultRouter %&gt;&lt;br /&gt; &lt;%= f.text_field :DefaultRouter %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :Netmask %&gt;&lt;br /&gt; &lt;%= f.text_field :Netmask %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :Broadcast %&gt;&lt;br /&gt; &lt;%= f.text_field :Broadcast %&gt; &lt;/div&gt; &lt;div class="field"&gt; &lt;%= f.label :Notes %&gt;&lt;br /&gt; &lt;%= f.text_field :Notes %&gt; &lt;/div&gt; **&lt;div class="field"&gt; &lt;%= f.label :multicast %&gt;&lt;br /&gt; &lt;%= f.check_box :multicast %&gt; &lt;/div&gt;** &lt;div class="actions"&gt; &lt;%= f.submit %&gt; &lt;% end %&gt; </code></pre> <p>Migration:</p> <pre><code>class AddMulticast &lt; ActiveRecord::Migration def up add_column :subnets, :multicast, :boolean, :default =&gt; 0 end def down remove_column :subnets, :multicast end end </code></pre> <p>I know I'm probably missing some small piece of code. Any help would be appreciated!</p>

    3. COnash, I added the rest of that code. Amar, I tried both as such: <%= f.check_box :multicast, :checked => true %> and: <%= f.check_box :multicast, :checked => 'checked' %> neither seemed to work. Did I do it right?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
